The 50-year-old actor and rapper unexpectedly jumped on stage to deliver a portion of Jaden's song "Icon" for a packed crowd at the desert festival's Sahara Tent. Jaden, 20, was all smiles as he recorded his dad's cameo and later posted it to social media.
For his performance, Papa Smith rocked a black T-shirt with the title of Jaden's new album, Erys Is Coming, and gray joggers. Watch below.
"Done Did 'dat! #coachella," Will captioned the clip on Twitter and Instagram. Jaden, meanwhile, posted an onstage selfie, writing, "I Love You Coachella."
Last year, Will Smith starred in a hilarious spoof of the music video for "Icon" to salute his son's music reaching 100 million streams.
Will wasn't the only Smith family member to crash Jaden's Coachella performance. During Jaden's first set on the first weekend, his sister Willow Smith made a surprise appearance along with friend Jordyn Woods.
